<p>
The <code>Template::Constants</code> modules defines, and optionally
exports into the caller's namespace, a number of constants used by the <a
href="../../modules/Template.html">Template</a> package.
</p>
<p>
Constants may be used by specifying the <code>Template::Constants</code>
package explicitly:
</p>
<pre>use Template::Constants;
print Template::Constants::STATUS_DECLINED;</pre>
<p>
Constants may be imported into the caller's namespace by naming them as
options to the <code>use Template::Constants</code> statement:
</p>
<pre>use Template::Constants qw( STATUS_DECLINED );
print STATUS_DECLINED;</pre>
<p>
Alternatively, one of the following tagset identifiers may be specified
to import sets of constants: '<code>:status</code>',
'<code>:error</code>', '<code>:all</code>'.
</p>
<pre>use Template::Constants qw( :status );
print STATUS_DECLINED;</pre>
<p>
Consult the documentation for the <code>Exporter</code> module for more
information on exporting variables.
